??? can be filled by FA, trade, or keeping some of the current players under TNSE that are not listed (and a few maybe from this years draft depending on birthdate and skill).

Some assumptions have been made:
*lower progression, obviously anyone can jump up but I'd like to not count on such things
*Trouba spending 3-4 years college, thus maximizing development time and ready to jump in to non-sheltered minutes
*I considered minimal regression in 2 years for our top players
